It was a poor design. I called it out a while back and guessed that it would be an issue once people got more hours on them. My laser edition is still down because of it. Ill probably just order a new toolhead and use some permanent loctite. After a couple back and forths with support, I remembered why I hated bambu support. Its a pressure fitted part in a machine that constantly heat cycles. Pretty obvious this would be an issue over time. As the part starts to slide off, it pinches the filament in its path. Probably what causes extruder issues for people in this forum. They just havnt realized yet.
@LarryCnAZ has the right idea. CA glue weakens when heated
